IMPROVEMENT IN EXTRACTORS FOR REVOLVING FIRE-ARMS.l

Specication forming part of Letters Patent No. 204,337, dated May 28,1878 application filed February 23, 1878.

To all whom t may concern:

Beit known that I, BENJAMIN F. JosLYN, of Worcester, in the State ofMassachusetts, have invented a new and useful Improvement in RevolvingFire-Arms; and that the following 'is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings,making a part of this specification, and to the letters of referencemarked thereon.

The object .of my invention is to eject the shells in rapid successionfrom the chambers of a cylinder of a revolving fire-arm; and it consistsof an ejector-bar having a projection on its rear end, its forward partbeing adapted to slide in a socket with a rearwardprojecting camthereon, arranged to impin ge against the forward end of the cylinder,and held in contact therewith by a spring, and held forward out of suchcontact by a screw turned onto a stem on the forward end of theejector-bar and against the front of the socket, as will be more fullyhereinafter described.

Figure I is a perspective view of a revolving lire-arm having myinvention applied thereto. Fig. II is a horizontal section Qf thecylinder and ejector, showing the latter thrown back, as in ejecting ashell. Fig. III is a horizontal section of the same, showing the ejectorheld forward, so that it will not operate to eject a shell; and Fig. IVis a vertical longitudinal section of that part of the ejector-bar whichforms the cam against which the cylinder strikes at the front ends ofthe chambers, to operate the ejector in ejecting the shells.

In the drawings, A represents the frame of a revolving fire-arm B, thebarrel; C, the cylA inder; and D, a side piece or socket secured to theside of the frame,A or to the rear part of the barrel in front of thecylinder, in which is arranged to slide the stem t' and forward part ofthe ejector-bar E, thelatter having a somewhat sharp-pointed projection,a, thereon, eX- tending inward a little toward the rear face of thecylinder C.

The stem t' extends through the socket D, and has a screw-thread madethereon, with a thumb-screw, F, turned thereon; and on the front part ofthe rod, in rear of the stem z', is a projection, c, extending rearward,and beveled on its upper side, at the extreme rear end, as shown clearlyin Fig. IV, and a spring, e, is placed within a recess in the socket,with its rear end bearing against the forward end' of the ejectorbar, toforce the latter rearward in a direction nearly parallel with thechambers of the cylinder.

The operation of my invention is as follows: The cartridges beinginserted into the chambers of the cylinder, the thumb-screw F is turnedup firmly against the front side of the socket D, which draws theejector-bar E forward with the projection a close to the rear face ofthe cylinder, as shown in Fig. III. The cylinder may then be rotated andthe arm discharged. The thumb-screwF is then turned partially off thestem z' and away from the front side of the socket D; and if thecylinder is turned With one of its chambers in line with theprojection'c the latter will project into the chamber and allow theejector-bar E to be forced by the spring e rearward a short distance,with the projection a a little in the rear of the cylinder, as shown inFig. II. This be- O ing the position of the ejector when required foruse, when the cylinder is rotated with the ngers every time the metal ofthe cylinder forming the partition between the two chambers comes incontact with the cam c the bar E is moved forward, and when thepartition passes said cam the spring e forces the bar E quicklyrearward. As the cylinder is revolved the forward movement of the bar'Eoccurs before the shellreaches the line of lsaid bar, so that as theshell passes into the line of the ejector-bar, the projection a being inthe position shown in Fig. III, the flange of the shell passes in therear of the said projection, and when the shell and the chamber whichcontains it are in. direct line withthe bar the cam c passes off the endof the cylinder into the front end of the chamber, and the spring cforces the bar E quickly and smartly rearward,.and the shells areejectedfrom the rear endsof the cylinder-chambers in rapid succession asthe cylinder is rotated.

The socket D may be made in a separate piece from the barrel or frameand attached thereto, as shown in the drawings; or it may eem o, and thespring e and socket D, alsul stantially as herein described.

BENJAMIN F. JOSLYN.
